Report #27303
[synthesis] Building agents as simple linear chains of prompts causes them to lose context in long tasks and makes human-in-the-loop impossible
Architect agents as stateful graphs with checkpointing, allowing pausing, resuming, and branching based on human feedback or tool outputs
Journey Context:
Early agents were stateless chains. LangGraph's architecture introduces a persistence layer \(checkpointer\) that saves the state after every step. This allows the agent to wait for human approval, recover from errors, and maintain a consistent memory across long-running tasks without blowing up the context window. It shifts agents from ephemeral scripts to durable workflows.
